To join, you must be an FTDNA customer and have either an L21+ result from FTDNA, an S145+ result from Ethnoancestry, or an rs11799226=G result from 23andMe.

M222+ men, although they are also L21+, are encouraged to join the M222 Project rather than this new one.

If you are SRY2627+ (M167+) or U152+, you are L21- and cannot join the R-L21 Plus Project.

If you are L21+, you can join this new project by following these directions:

Click on the little "Join" icon on the left side of the screen from your FTDNA home pages. Then scroll down to the "Search" box. Click on the little drop-down box on the left and change "Equals" to "Contains." Type "L21" (without the quotes) in the Search box and click on Search.

This is a reminder to any and all who has received either {a} an L21+ result from FTDNA, {b} an S145+ result from EthnoAncestry, or {c} a "G" (derived) result for rs11799226 from 23andMe, and has a kit with FTDNA, but has not yet joined up with FTDNA's R-L21 Project

It is good to see another Celtic project up and running.Thats three now and I'm sure there will be a lot more before the year is out.

Well, there's a wee bit o' controversy about the "Celtic" categorization for L21, but it sure does seem to correlate nicely, doesn't it?

Rich is endeavoring to make the Celtic-studies academic community aware of its possible significance.

As far as I'm concerned, the controversy is more over identifying all of P312 with the Celts than for L21. However I believe the jury is still out on L21. We know it has a presence in Scandinavia, though not yet how strong a presence. I don't believe we have any idea of what the distribution of L21 to the east is going to be, assuming it is fact to be found there.
